Just wrote this lengthy reply and it got eaten by the forums! Arrgh!
Anyway the gist of it was, similar to you I put on over 10kgs in just a little over a year. I looked back to changes it my habits at that time (easy for me, it went back to when I started full time work
) and I worked it from there... Has there been any big changes in your habits/lifestyle over the past 18months? And what is a way to combat them?
Regarding your question on shakes, personally I tried Tony Ferguson and had no success. That said, I know of good friends in real life (and I think a few people on this forum too) who have been on shakes and done well for themselves. I agree that it isn't for long-term goals, but can be great for a 'kick-start' your new lifestyle. And I don't know anybody except me
who went backwards
